GitHub Pages "Normal" Setup for User & Organization Pages

Let’s say your GitHub username is “alice”. If you create a GitHub repository named alice.github.com, commit a file named index.html into the master branch, and push it to GitHub, then this file will be automatically published to http://alice.github.com/... The same works for organizations.

Read more here: http://pages.github.com/

However... the downside of this is that anyone that forks this repo won't get it as a GitHub Pages repo when they are working on it... because they have a different GitHub "username" (or "organisation name").

So the trick is to not use a master branch as the documentation tells you... rather, use a gh-pages branch, as you would for your other "Project Pages".

Overview

Geth (Go-Ethereum) as of January 2022 takes about 500 GiB of space on a fast/snap sync, and then grows by ~ 10 GiB/week. This will fill a 1TB SSD in ~6 months, to the point where space usage should be brought down again with an offline prune.

Happily, Geth 1.10.x introduces "snapshot offline prune", which brings it back down to about its original size. It takes roughly 4 hours to prune the Geth database, and this has to be done while Geth is not running.

Caveat that while several folx have used offline pruning successfully, there is risk associated with it. The two failure modes we have seen already are:

• There is 25 GiB or less of free disk space
